ABOUT PHA

PHA (Polyhydroxyalkanoates) are natural aliphatic polyesters, synthesized through the fermentation of sugar and lipids by a wide variety of bacteria. Its characteristics are similar to those of polypropylene, but it is biodegradable. The bio-degradation process usually takes place with enzymes.

PHA polymers are thermoplastics and can be cultivated/treated with equipment for processing conventional plastics. PHA plastics are UV stable; they withstand temperatures of up to 180 degree Celsius and rarely leak water.  

Metabolix, Inc has developed a cost-effective method for manufacturing PHAs that allows them to be produced by microorganisms, and therefore makes them biodegradable by similar organisms present in environments including soil and water.
